Umgubo wegrafiti ucutshungulwa kwigrafiti eyandisiweyo okanye igrafiti eguquguqukayo. Iindidi zephepha legrafiti zinokwahlulwa zibe liphepha legrafiti eguquguqukayo, iphepha legrafiti yokutywina, iphepha legrafiti elibhityileyo kakhulu, iphepha legrafiti eliqhuba ubushushu, njl. Kwicandelo lokutywina lemizi-mveliso, iphepha legrafiti yokutywina lelona lisetyenziswa kakhulu. Iindidi zephepha legrafiti eguquguqukayo, iphepha legrafiti yokutywina, iphepha legrafiti elibhityileyo kakhulu, njl. zonke ziphelele kakhulu kwaye zineendlela ezahlukeneyo zokusebenza kwimizi-mveliso.
Iphepha legrafiti lenziwe ngegrafiti eyandisiweyo ngokucinezela, ukuqengqeleka kunye ne-calcination. Linokumelana nobushushu obuphezulu, ukuqhuba ubushushu, ukuguquguquka, ukuqina kunye nokusebenza kakuhle kokuvala. Iphepha legrafiti elisemgangathweni ophezulu lisebenza kakuhle kakhulu ekuvaleni, lincinci kwaye lilula ngobunzima, kwaye kulula ukulisika. Ngenxa yeempawu zalo zokuvala kunye nokuqhuba ubushushu, iphepha legrafiti lisetyenziswa kakhulu kwiindawo zokuvala kunye nokusasaza ubushushu kwimizi-mveliso. Iphepha legrafiti elisetyenziselwa ukuvala lincinci kwaye lineengenelo zokuba kulula ukulisika nokulicubungula, alinabushushu, aligugi, alinamhlwa, lisebenza kakuhle ekuvaleni kunye nomjikelo omde wokutshintsha. Iingenelo zephepha legrafiti zokuvala zidlale indima ebaluleke kakhulu kwicandelo lokuvala imizi-mveliso. Ezi ngenelo zephepha legrafiti zokuvala zinokuhlangabezana neemfuno zokuvala imizi-mveliso. Iphepha legrafiti lokuvala linokulungiswa libe yimigca yokuvala igrafiti, imingxunya yokuvala igrafiti, iigasket zokuvala igrafiti, ukupakisha igrafiti kunye nezinye iimveliso zokuvala igrafiti. Lingasetyenziselwa ukuvala kwiindawo zokudibana kwemibhobho, iivalvu, iipompo, njl.njl., kunye nokuvala oomatshini ngokuguquguqukayo nangokungagugiyo. Ukusebenzisa iphepha legrafiti ukutywina njengezinto ezisetyenziswa kwiindawo zokutywina igrafiti. Isebenzisa ngokupheleleyo iingenelo zephepha legrafiti zokutywina kwaye sisixhobo esibalulekileyo kwimveliso yokutywina yemizi-mveliso. Iphepha legrafiti lidlala indima ebaluleke kakhulu kwicandelo lokutywina nokusasaza ubushushu.
Ngokukhawuleziswa kokuphuculwa nokutshintshwa kweemveliso ze-elektroniki kunye nemfuno ekhulayo yolawulo lokusasazwa kobushushu kwezixhobo ze-elektroniki ezincinci, ezidityaniswe kakhulu nezisebenza kakuhle, itekhnoloji entsha yokusasazwa kobushushu kwiimveliso ze-elektroniki nayo iye yaziswa, oko kukuthi isisombululo esitsha sokusasazwa kobushushu sezinto ze-graphite. Esi sisombululo se-graphite sendalo esitsha sisebenzisa ubuchule bokusasazwa kobushushu obuphezulu, indawo encinci kunye nobunzima obuncinci bephepha le-graphite. Siqhuba ubushushu ngokulinganayo kuzo zombini iindlela, sisusa iindawo "ezishushu", kwaye siphucula ukusebenza kwee-elektroniki zabathengi ngelixa sikhusela imithombo yobushushu kunye nezinto ezisetyenziswayo.
Iphepha legrafiti yimveliso yegrafiti eyenziwe ngokunyanga iikhemikhali igrafiti ye-phosphorus flake enekhabhoni ephezulu ize emva koko ibekwe kwindawo yokwandiswa nokuqengqeleka ngobushushu obuphezulu. Isebenza njengesixhobo esisisiseko sokwenza izitywina ezahlukeneyo zegrafiti.
Eyona misebenzi yayo iphambili: Iphepha legrafiti, elaziwa ngokuba liphepha legrafiti, lisebenzisa ithuba lokumelana nobushushu obuphezulu kunye nokumelana nokugqwala.
Umgubo wegrafiti
Isici sokukwazi ukuqhuba umbane kakuhle senza ukuba sisetyenziswe kwi-petroleum, ubunjineli beekhemikhali kunye ne-elektroniki. Izixhobo okanye izinto ezinobuthi, ezinokutsha nezishushu kakhulu zinokwenziwa zibe yimicu eyahlukeneyo yegrafiti, izizalisi, iigasket zokutywina, iipleyiti ezidityanisiweyo, iigasket zesilinda, njl.njl.
Ngokukhawuleziswa kokuphuculwa nokutshintshwa kweemveliso ze-elektroniki kunye nemfuno ekhulayo yolawulo lokusasazwa kobushushu kwezixhobo ze-elektroniki ezincinci, ezidityaniswe kakhulu nezisebenza kakuhle, itekhnoloji entsha yokusasazwa kobushushu kwiimveliso ze-elektroniki nayo iye yaziswa, oko kukuthi isisombululo esitsha sokusasazwa kobushushu sezinto ze-graphite. Esi sisombululo se-graphite sendalo esitsha sisebenzisa ubuchule bokusasazwa kobushushu obuphezulu, indawo encinci kunye nobunzima obuncinci bephepha le-graphite.

Eyona ndlela iphambili yokusebenzisa obu buchwephesha butsha bephepha legrafiti: Busetyenziswa kwiikhompyutha zeelaptop, izikrini zepaneli ezisicaba, iikhamera zevidiyo zedijithali, iifowuni eziphathwayo kunye nezixhobo zokuncedisa umntu, njl.
1. Ukukhutshwa okungazinzanga ekuqaleni kokucubungula
Isizathu sokwenzeka:
Kwinqanaba lokuqala lomatshini wombane ngee-electrode ze-graphite, ngenxa yendawo encinci yoqhagamshelwano lomsebenzi okanye ubukho beetships kunye nee-burrs ezisikiweyo, ukukhutshwa okuxineneyo kwenzeka. Ngaphezu koko, ngenxa yamandla amakhulu okukhutshwa (umbane ophezulu kunye nobubanzi be-pulse ebanzi), ngelixa isithuba se-pulse sincinci kakhulu kwaye uxinzelelo lwe-jet luphezulu kakhulu, ukukhutshwa akuzinzanga ekuqaleni kokucubungula, kwaye kwenzeka neziganeko zokutsala i-arc.
Isizathu sokwenzeka:
Kwinqanaba lokuqala lomatshini wombane ngee-electrode ze-graphite, ngenxa yendawo encinci yoqhagamshelwano lomsebenzi okanye ubukho beetships kunye nee-burrs ezisikiweyo, ukukhutshwa okuxineneyo kwenzeka. Ngaphezu koko, ngenxa yamandla amakhulu okukhutshwa (umbane ophezulu kunye nobubanzi be-pulse ebanzi), ngelixa isithuba se-pulse sincinci kakhulu kwaye uxinzelelo lwe-jet luphezulu kakhulu, ukukhutshwa akuzinzanga ekuqaleni kokucubungula, kwaye kwenzeka neziganeko zokutsala i-arc.
Isisombululo:
1. Ngaphambi kokuba kucutshungulwe, kuyimfuneko ukususa ngokupheleleyo iitships kunye neeburrs ezinamathele kwindawo yokusebenza, kunye neefilimu ze-oxide, ii-coating, i-rust kunye nezinye izinto eziveliswa kunyango lobushushu lwendawo yokusebenza.
2. Beka umbane ngexabiso eliphantsi ekuqaleni. Emva koko wonyuse kancinci kancinci uye kwi-peak current uze ubeke uxinzelelo lwe-jet lube luncinci.
2. Iiprotrusions zegranular ziyaveliswa
Isizathu sokwenzeka:
1.Ukuba ububanzi bepulse bubekwe bukhulu kakhulu, iiprotrusions zegranular ziya kwakheka kwiikona ze-electrode, nto leyo enokubangela i-short circuit kwaye ikhokelele ekukhutshweni kwe-arc.
2. Kukho iitshiphusi ezininzi kakhulu zokucubungula iimveliso ze-electro-erosion, ezingenakukhutshwa ngexesha. Ukuba i-Angle ye-nozzle ye-processing fluid ayimiselwanga kakuhle, ulwelo lokucubungula alunakufakwa ngokupheleleyo kwisithuba, kwaye iimveliso ze-electro-erosion kunye neetshiphusi zokucubungula azinakukhutshwa ngokupheleleyo. Xa ubunzulu bokucubungula bunzulu kakhulu, iitshiphusi zokucubungula azinakukhutshwa ngokupheleleyo kwaye zihlale ezantsi.
Isisombululo:
1.Nciphisa ububanzi be-pulse (Ton), yandisa i-pulse interval (Toff), kwaye ucinezele ukuveliswa kwee-granular protrusions kunye nokwenziwa kweemveliso zombane kunye nee-processing chips.
2. Zama ukubeka umlomo ecaleni kwe-electrode. Ukuba ubunzulu bokucubungula bunzulu kakhulu,
3. Yandisa inani lokutsiba kwe-electrode, khawulezisa isantya sokutsiba, kwaye unciphise ixesha lokukhupha.
3. Ukuxinana kwenzeka kumphezulu ongaphantsi ngexesha lokucubungula
Isizathu sokwenzeka:
Ngexesha lenkqubo yokugaya umbane, ukuba ixesha lokubetha kwentliziyo lincinci kakhulu, isantya sokutsiba phezulu nasezantsi kwe-electrode sicotha, kwaye uxinzelelo lwejethi lubuthathaka, iitships zokucubungula zeemveliso zombane zokukhukuliseka azinakukhutshwa ngokupheleleyo. Ngaphezu koko, iimveliso ezininzi zokukhukuliseka kombane zinamathela kumphezulu osezantsi we-electrode, zenze iibhloko ze-carbonized, ezinokuthi ziqhekeke ngexesha lokuhamba phezulu nasezantsi kwe-electrode, nto leyo ebangela ukuxinana kumphezulu osezantsi wokucutshungulwa.
Isisombululo:
1. Yandisa ixesha lokubetha kwentliziyo.
2. Yandisa isantya sokutsiba kwe-electrode.
3. Nyusa uxinzelelo lwejethi.
4. Sebenzisa ibrashi ukucoca iitships zomatshini ukusuka ekupheleni kwe-electrode kunye nomphezulu osezantsi wokucubungula.
4. Ukurhabaxa okungalinganiyo kunye nokugoba komphezulu ongaphantsi
Isizathu sokwenzeka:
Ngenxa yesithuba esincinci kakhulu se-pulse, uxinzelelo lwe-jet alulingani, umsantsa phakathi kwee-electrode umncinci kakhulu, kwaye iimveliso ze-electro-erosion azinakukhutshwa ngokupheleleyo. Ngaphezu koko, zisasazwa ngokungalinganiyo kumphezulu osezantsi wokucubungula. Njengoko ukucubungula kuqhubeka, ukugoba kwenzeka kumphezulu ongezantsi okanye uburhabaxa bomphezulu osezantsi wokucubungula abulingani.
Isisombululo:
1.Nyusa ixesha lokubetha kwentliziyo uze usete uxinzelelo oluqhubekayo lwejethi.
2. Yandisa umsantsa phakathi kwe-electrode kwaye ujonge imeko yokususwa kwe-chip rhoqo.
